With the reduction in vehicles powered by fossil fuels, lithium ion batteries have become more prevalent, with many automobile manufacturers pushing to produce highly efficient electric vehicles. This has pushed the production of lithium to the forefront of peoples' minds; however, another component of these batteries is just as vital. Carbonaceous materials have always been the most important aspect of the anode of rechargeable lithium ion batteries, because of their higher specific charges and lower redox potentials than other candidate materials. Graphite is the most common anode material, and as such should not be neglected. In addition to batteries, graphite is used in brake linings, lubricants, powdered metals, refractory applications, and steelmaking. This Collaborative Research and Development (CRD) Grant proposal aims at generating new knowledge related to processing of graphite from its ores, and the purification through sustainable aqueous processing routes. It is in collaboration with SRG Graphite, to be undertaken in the Department of Mining and Materials Engineering at McGill University. This project will be headed by Prof Kristian Waters and Prof Sidney Omelon, and will encompass mineral processing and aqueous processing routes to produce a high-grade concentrate to be used in different applications, including battery anodes. SRG Graphite will be active in all aspects of this collaborative research project, which will place Canadian companies at the forefront of this growing market, and enable the sustainable development of a mineral resource that has important economic value to Canada.

随着化石燃料驱动车辆的减少，锂离子电池变得更加普遍，许多汽车制造商都在努力生产高效的电动汽车。 这使得锂的生产成为人们关注的焦点；然而，这些电池的另一个组件同样重要。 碳质材料一直是可充电锂离子电池阳极最重要的方面，因为它们比其他候选材料具有更高的比电荷和更低的氧化还原电位。 石墨是最常见的阳极材料，因此不应被忽视。 除了电池之外，石墨还用于制动衬片、润滑剂、粉末金属、耐火材料应用和炼钢。 这项合作研究与开发 (CRD) 拨款提案旨在产生与从矿石中加工石墨以及通过可持续水处理路线进行纯化相关的新知识。 该项目与 SRG Graphite 合作，由麦吉尔大学采矿与材料工程系进行。 该项目将由 Kristian Waters 教授和 Sidney Omelon 教授领导，涵盖矿物加工和水处理路线，以生产用于不同应用（包括电池阳极）的高品位精矿。 SRG Graphite 将积极参与该合作研究项目的各个方面，该项目将使加拿大公司处于这一不断增长的市场的前沿，并实现对加拿大具有重要经济价值的矿产资源的可持续发展。
